This drama kept me watching and had to force myself to go to sleep or I would have stayed up all night. The two main characters were great. Very interesting plot which kept me guessing. Yuna performed this role just excellent for such a young age. At first I just thought she was older but looked really young and that is the reason she was selected. I looked her up and she is actually very young. She a great performer.
Yoon Kye Sang also did a great job. He must have gained weight for this role. He looks totally different. Loved his performance. Great job on the writing of this story.
